One of Kelly Osbourne's Diet Tricks? Colored Plates!

Earlier this year, we reported on a study in the Journal of Consumer Research, which found that when people serve food on plates that are colored very differently from the food, they serve 21 percent less. For example: pasta with red sauce on a bright white plate creates an optical illusion of sorts, tricking you into serving a smaller portion than you might with red sauce on a red plate.

It's seems like the contrasting-color trick could be another tool in eating mindfully: something to help us slow down and notice what and how we're eating, instead of just scarfing it (as we busy ladies can sometimes do).

Would you try this little trick? Do you have any portion-control tips of your own? How do you measure out serving sizes (if you do)?
